Abstract (en)
[origin: WO2010142394A1] The invention relates to a method and a device for monitoring a fluid system of an extracorporeal blood treatment device, comprising an extracorporeal bloodstream I having an arterial blood line 5 leading to a first chamber 3 of a dialyzer 1 or filter, which is divided by a semipermeable membrane 2 into the first chamber 3 and a second chamber 4, and having a venous blood line 6 leading out of the first chamber 3 of the dialyzer 1 or filter. In the method according to the invention and the device according to the invention, the pressure in a ventilation line (12) branching off the venous drip chamber 8 in the venous blood line 6 is measured, a hydrophobic filter 16 being disposed in the ventilation line. A fault in the fluid system is determined in the absence of pressure variations in the segment of the ventilation line 12 remote from the venous drip chamber 8. The pressure variations in the ventilation line 12 can be generated downstream of the hydrophobic filter 16 by alternately ventilating the ventilation line that is closed downstream of the hydrophobic filter during blood treatment.
